We couldn’t avoid using unnatural light for taking our photos, so we were wondering how that will work for when we are generating the cone catch model. In the video it is done by taking a picture of the colour standard under natural light. For our situation to generate cone catch model for the camera should we take a photo of the colour standard under natural light or the light the photos were taken under? We know that the spectrum of the lights we are using differs from natural light spectrum. For generating our model we are using the colour checker standard and the values found in the mica tool box for the colour checker reflectance (each standard having its value found by averaging its visible light values), is it okay to use those values of reflectance under unnatural light?

Thank you for your time and help!
